WHAT ROLE DOES METABOLISM PLAY IN GAINING WEIGHT? YOU MAY BE SURPRISED TO FIND OUT THE ANSWER. METABOLISM REGULATES THE ENERGY THAT OUR BODIES NEED. IT IS A SYSTEM THAT NEVER RESTS, AS ALL OF OUR BODY FUNCTIONS REQUIRE ENERGY. WE REQUIRE ENERGY TO BREATHE, PUMP BLOOD, DIGEST FOOD, GROW AND HEAL! WHEN YOU EAT OR DRINK, YOUR BODY COMBINES WHAT YOU INGEST WITH ENZYMES TO BREAK THEM DOWN TO MEET THE ENERGY LEVELS OUR BODY NEEDS.
metabolism in the body
The energy required to breathe, pump blood, and digest food is much higher than the energy required for exercise. The body’s natural processes make up about 70% of your daily calorie expenditure. The use of calories by your body for these natural processes is called basal metabolic rate (BMR) or resting metabolic rate (RMR).
What causes bmr to change from person to person?
People with larger frames and a larger amount of muscle will usually burn more calories. This also applies to the natural body functions like breathing, pumping blood, and food digestion.
As you age, your body burns calories at a slower rate, usually linked to slower hormone production.
Men tend to have a higher ratio of muscle-to-fat, so they tend to burn calories at a higher rate.
did you know?
FOOD PROVIDES THE BODY WITH MOST OF THE ENERGY IT NEEDS, BUT IT ALSO NEEDS TO BE BROKEN DOWN. THE PROCESS OF FOOD BEING BROKEN DOWN IS CALLED THERMOGENESIS, AND IT TAKES ABOUT 10-13% OF THE ENERGY YOU GET FROM FOOD TO TURN IT INTO SOMETHING TO USE. THE LAST PROCESS THAT BURNS A CONSIDERABLE AMOUNT OF ENERGY IS PHYSICAL ACTIVITY. RUNNING, BIKING, OR PLAYING WITH YOUR PET BURNS ENERGY, AND THE AMOUNT OF ENERGY EACH DAY CAN CHANGE. PHYSICAL ACTIVITY MAKES 30-35% OF YOUR ENERGY REQUIREMENTS. IT IS THE MAJOR FACTOR THAT CONTRIBUTES TO WEIGHT GAIN OR WEIGHT LOSS.
YOUR BODY’S METABOLISM DEPENDS ON CERTAIN HORMONES. THIS IS WHY WHEN YOU’RE YOUNGER AND YOUR HORMONE LEVELS ARE OPTIMAL, YOUR BODY BREAKS DOWN FOOD FASTER AND THEREFORE IT’S EASIER TO MAINTAIN A HEALTHIER WEIGHT. THIS IS WHY ACHIEVING OPTIMAL HORMONE LEVELS IS ESSENTIAL FOR LOSING AND SUSTAINING A HEALTHY WEIGHT.
